How Much Does Interior Design Cost in the UK?

The truth is, there isn’t one fixed answer.
Interior design fees vary depending on the project’s scale, the level of detail, whether 3D visualisations are included, the designer’s experience, and even the region — what you’ll pay in London is very different from Aberdeen or Glasgow.
Let’s look at how UK interior design pricing works, the different models designers use, and what you get for your investment.

Different ways designers charge for their services

1. Price per square metre

Pricing per square metre is a widely used and transparent approach within the interior design industry, particularly for residential and boutique commercial projects.

With this model, the cost is calculated based on the total area of the space and typically varies depending on several key factors — the complexity of the project, the scope of services, and whether the design package includes 3D visualisations.

Across the UK market, interior design fees under this structure generally start from around £50 per square metre for projects without 3D visualisations, focusing on space planning, technical drawings, and material specifications.
For more comprehensive packages that include detailed 3D visualisations and advanced design development, fees increase accordingly.

Pricing can also vary significantly by location. In major cities such as London, full design services may reach £300–£350 per square metre, reflecting higher project complexity, expectations, and market conditions.

This model offers clients a clear understanding of costs while allowing flexibility based on the specific needs and scale of each project.

2. Hourly rate

An hourly rate is often used for consultations, small-scale projects, or decorative styling.
Average rates across the UK:

• £50–£120/hour in Aberdeen, Glasgow, and Edinburgh
• £100–£250/hour in London, depending on the designer’s experience and portfolio.

This option is ideal if you need targeted help — such as selecting furniture, finishes, or lighting schemes — without a full design package.

3. Percentage of the total project cost

For large projects, many UK designers charge 10–20% of the total build or renovation cost.
This is common in luxury residential and commercial developments, especially in London and major Scottish cities.
It’s a fair structure because the designer’s compensation reflects the project’s scale — they’re responsible for maintaining both aesthetics and cost-efficiency.

4. Fixed fee

Some designers prefer to set a single, fixed price after an initial consultation and project brief.
This works best for smaller, well-defined projects — for example, a kitchen refurbishment or a single-room redesign.

5. Monthly or retainer fee for author supervision

After the design is complete, clients often want ongoing guidance during the construction phase.
This service — author supervision — ensures that everything is executed exactly according to the design intent.
At Yuliya Forrest Interior Design, author supervision can be arranged:

• Per hour, for individual visits or consultations on site; or
• Per month / per phase, depending on project complexity and location.

This includes checking the quality of work, verifying material selections, assisting with on-site decisions, and coordinating with contractors.

6. Full-service procurement and financial management

Some clients prefer a completely hands-off experience — when the designer not only supervises, but also takes full responsibility for procurement, logistics, and budget control.
In this model, the designer:

• Places and manages all orders directly with suppliers and manufacturers
• Tracks deliveries, quality, and replacements
• Coordinates payments and lead times
• Ensures that all purchased items align perfectly with the approved design concept

Because this level of service involves financial responsibility and continuous management, it is typically charged as a percentage of the total procurement budget — often 10–15%, depending on scale and complexity.
This option is ideal for clients who want the entire project handled from start to finish — with no stress, no calls from builders, and one accountable professional overseeing every stage.

 Cost variations across the UK

Aberdeen, with its blend of history and innovation, offers clients the chance to create truly timeless interiors — often at more competitive rates than in southern England.

What’s included in a professional design package

Although details vary between studios, most full-service packages include:

• Concept development and moodboards
• Detailed floor plans and zoning
• Lighting and electrical layouts
• Material and furniture selection
• 3D visualisations or hand-drawn sketches (if applicable)
• Specifications for builders and suppliers
• Procurement coordination
• Optional author supervision or full project management

Each phase is carefully structured, ensuring that the final result is cohesive, functional, and visually refined.

Why Interior Design Is Worth It

A well-designed space does more than look good — it transforms the way you live, work, and feel.
A professional designer helps you avoid costly mistakes, source the right materials, and create an environment that is both practical and emotionally uplifting.
As Yuliya Forrest says:
“You’ll spend money on construction either way — the question is whether you want to pay for a result that frustrates you, or one that delights you for years.”
However, Yuliya also warns clients to choose carefully.
In the UK — and especially online — it’s common to see people calling themselves “interior designers” after completing only a few months of short courses. While some of them can handle décor or colour selection, this level of training is not enough for serious design work that involves spatial planning, electrics, plumbing, or structural layout changes.
“If you are hiring an interior designer, make sure they have a proper architectural or construction background,” Yuliya explains. “Design is not just decoration — it’s a discipline that combines art, engineering, and human psychology.”
With both a Fine Arts degree and a Civil Engineering background, and nearly 20 years of experience, Yuliya Forrest bridges creativity and technical precision.
She understands every stage of the process — from initial concept to construction and final styling — ensuring that your project is not only beautiful, but also safe, functional, and expertly executed.

Final thoughts

Interior design in the UK ranges from £45/m² to £250/m², depending on location, scope, and level of service.

But behind those numbers stands expertise, coordination, and vision — things that turn renovation from stress into an experience of beauty and precision.
